IMPRovie-MENT iN MACHINES FOR MOLDINGFABRICS.

Specification formng partlo'f-'Letters Patent N o. 1774,83 l, dated May 23, 1876; application filed i t April 1, 1816.

To all whom t may concern:

of the cityf and county of Philadelphia, and

. State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Molding Paper, Fabric,l and other pliable substances and I do hereby declare the following to be a clear and enact description of the nature thereof, sufficient to enable othersskilled in4 the art to which my invention appertains, to fully understand, make, and use the same, rcferencebeinghad to the accompanying drawings, making part of ,this speclicatioii, in Which- Figure lis a side view of l the apparatus embodying my invention. Fig. 2is a top or plan view thereof. Fig. 3 is a central longitudinal .vertical section thereof.

Similar letters of reference indicate corret spoiidingparts inthe several'gures.

v `My invention` consists o'f abelt or coi'iveyer,

which is located lbeneath the die orithe bedy thereof,"of `a machine lfor cutting, stamping, punching, or otherwise'sliapingpieces of pliable substances, whereby the work may belinspected'as it leavestlie die and conveyed to other apparatus to be further operated upon,

or to a place of collection. `It also coiisists'of a roller and a conveying-belt,- so combined that articles passed between the roller and belt will bei-eadily molded. It further consists of'an'a-Xial'frame or arm, and a screw ar# ranged relatively thereto, so as to tighten the coiiveying-belt.- Italso consists in passing theconveying-belt around a pulley, wliichisf ing channels, C, throughhwhich runs a horizontally-'extending endless belt or conveyei",

D, Whose supports are on rollers D( D1)7 the roller D being mounted on an arm or frame,

. E, pivoted tothe base A the roller D" mounted on an upright or support, F, secured to the base opposite the arm or frame E-,and the roller "D mounted oii an arm or frame, Gr,

`in which there are two'longitudinallyextendl which is pivoted to the uprightlor support F, Be it known that I, WILLIAM H. HART, Jr.,

the roller vD being located above the roller D. To the upright-or support F there is ,mounted a roller, H, which is arranged between the rollers D D, and is in contact With the outer surface of the endless conveyer D, so that the latter passes around said vroller H and the rollers D. D" D. To theiupriglit.

F there is secured, a chute, J, which'exteiids.

horizontally over the conveyer D, and traiis- Y versely'ther'eto, and has one end adjacent to A i pressingA against it, and thus imparts a mold or/j curved shape to said piece. As .soon as the piece has fully emerged from between the roller and conveyer it falls on the cliute J, and is thus 'directed to a place of discharge orcollection, or to other apparatus, so as to be further 4.

operated upon.' 1

ltwill be seen that the coiiveyer runs below the plate A, and ,thus the pieces of unmolded substaiice'falling thereonthrough the opeiiin g .a may be readily inspected, and if the work is not perfect or correct it will be perceived,

and attention may be paid thereto.

lThe degree of inoldingvto meet the requirements ot' various kinds ot'fwork may be readily adjusted by means of the arm or frame G. By moving said arm inwardly or iii a direction toward they plate A, the coiiveyer` D will envelop oi' lap a great extent of the roller H, .whereby the substance to be molded will be molded with a greater curve. By moving the arm outwardly, the conveyer will envelop or lap a less extent ot' the roller H, and thus the sub-V stance will befmolded withaless curve. When j fthe arm G is adjusted it will be held in its vpositioii by meansof set-screws b, wliich pass' through curved slots d iii the armv into the standard The conyeyer D may be tightened, as occay V sion requires, by means'of a screw,iK, which is fitted to a standard, L, risingv from the base A', and its head bears against a cross-bar, e,

veyer.

By rotating the screw in one direction the arm or frame E will be moved outwardly, and thus the conveyer -will be tightened. When the screw is rotated in the other direction the arm or frame is permitted tolnoveinwardly, and thus the conveyer will be slackened.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The bed B, with channels C C, in combination with the conveyer or belt D passedv therethrough, substantially as and for the pur- `poseset forth.

2. The endless conveyerD, -Ysupported'oni rollers D D, in. combination withan .elevatedi roller D, and the interposed 'molding-roller H, forming together an improvement in molding apparatus, substantially as and`v for the purpose set forth.

'Ihe'l combination, with the rollers'D D and molding-roller H, of the roller D', su pport- @ing therendless conveyer D, and. mounted on the adjustable tightening arm or frame E.

4.. The combination, with the roller D and 'molding-roller H, mounted on the support F of the elevated roller D, supporting the endless conveyer D, and mounted on the adjustavble arm or framev Gr, Which'is pivoted to said support F, substantially as and 'for the purpose set forth. f
